' Application filed October 8, 1923. Serial No. 667,308.

To all whom. it may concern.- Be it known that I, FRANK X. MANTBION,

a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Penns lvama, have invented a new and Improv Oil Burner, of which the following is a full, clear, and exact description.

This invention relates to improvements in heating apparatus, and has particular reference to an oil burner.

An object of the invention is to automatically control the flow of oil from a source of supply to the burner in such manner that upon the overflow of a predetermined amount of unconsumed oil from the burner the flow thereof from said source will be stop ed.

Another 0 ject is to provide an improved burner of simple and eflicient construction capable of being attached or otherwise associated with afurnace or other form of heating apparatus.

The above and other objects will appear more clearly from the following detail description, when taken in connection with the accompanying drawing, which illustrates a referred embodiment of the inventive i ea.

In the'draw' Figure 1 isa fragmentary sectional view of a furnace showing the improved oil burner associated therewith;

Figure 2 is a fragmentary elevation, partly broken away and shown in section, of a portion of the mechanism for controlling the flow of oil to the burner;

Figure 3 is a section on the line 3-3 of Figure 1;

Fi re a is a section on the line 4-4 of Figure 1, showing the lowermost coil of the burner in top plan view; and

Figure 5 is a section on the line 5-5 of Fi re 4.

ferring more particularly to the accompanying drawing, the numeral 6 indicates generally a furnace which may be of any construction and w ich includes the usual grate 7 and draft regulating door 8. Although the present invention is shown as applied to a furnace, it will be understood that the same may, with equal facility, be applied to other forms of heating apparatus, or utilized as a heating unit by itself.

In its a plication to the furnace 6 the burner is s own as comprising a casing or thereon a heatin drum {9, which is supported within the furnace d rectly overthe rate 7 thereof. This grate 18 also designed to support directly coil 10, the convolutions of WhlCh prefera 1y increase in size toward the upper end of the coil. The uppermost convolution of the coil is extended into a straight connection, the lower end of which termmates in a burner coil 12 formin one extremity of the pipe from which-the urner is constructed and bent in such manner that the plurality of openings 13 therein will be disposed beneath the convolutions of the coil 10. The openings or orifices 13 are tapered outwardly, as clearly shown in Figure 5, to provide s ace for an adequate flame which will afford the proper amount of heat and at the same time raise the temperature of the coil 10 to such an extent that the oil flowing through said coil will be vaporized to form a gas which is ignited at the openings 13.

The lowermost convolution of thecoil 10 is extended laterally therefrom to form the section 14 of the supply pipe, which section is projected through the outer wall of the furnace 6 and is joined at its outer endto the section 15 by means of the couplin 16. The manually operated valve 17 is uti ized 1 to control the flow of oil from a suitable source of supply (not shown) through the pipes 18 and i9 and into the section 14 from whence said oil is conveyed to the coil 10. An automatically controlled valve 20 is introduced into the pipe 19 adjacent its connection with the pipe 18 for the purpose of shutting off the supply of oil to the burner 12 after a predetermined amount of unconsumed oil has overflowed from said burner.

The mechanism for accomplishing the automatic control of the valve 20 preferably comprises a drip pan 21 supported directly beneath the grate 7 and burner coil 12 by means of an arm 22 extending from said pan and pivoted intermediate its ends at 23 in the opening closed by the door 8 of the furnace. The outer extremity of the arm 22 projecting beyond the door 8 is, provided with a counterbalancing weight 24 which normally maintains the drip pan 21 in a horizontal position, as shown in Figure 1 of the drawing. However, when a predetermined quantity of unconsumed oil has dripped from the burner coil 12 into the pan 21, the weight of said oil and pan will overbalance that of the weight 24 and the parts assume the position shown in dotted lines.

Associated with. the arm 22 is a trip mechanism including a supporting member 25 attached in any preferred manner to the section 15 and carryin at its lower end an angular frame 26. ivotally connected at 27 to one end of the frame 26 is a horizontally extending arm 28, the free end of which is connected by a link 29 to the arm 22 adjacent the weight 24. Carried by the arm 28 is a depending latch 30, the lower end of which normally supports the free end ofan arm 31 pivotall connected at 32 to the other extremity of t e frame 26. An operating member 33 for the valve 20 is connected at one end to said valve and is .bent intermediate its ends to provide an extension 34 normally supported in an elevated position by means of a hanger 35 detachably mounted upon the extension 34 and secured in position by means of a screw 36 or other suitable fastening device. The free or upper extremity of the hanger 35 is provided with a lateral extension 37 engageable over the arm 31 when the parts are in normal position to maintain the valve operating member 33 in its normal position. However, when the arm 22- moves to the dotted line position shown in Figure l, the upward movement of the outer end of said arm imparts a similar movement through the link 29 to the adjacent end of the arm 28. The latch member 30 being carried by said arm 28 swings to the dotted line position releasing the free end of the arm 31 and permitting it to drop to a vertical position. Under the influence of a weight 38 detachably secured to the extension 34 the valve operating arm 33 will be swung downwardly to the dotted line position shown in Figure 3, thereby operating the valve 20 to close communication between the pipes 18 and 19. In this manner, the flow of oil to the burner of overflow oil from the burner will thus be prevented. 4

What is claimed is:

1. In an oil burner, a coil, a supply pipe therefor, a valve in said pipe for controlling the flow of oil therethro-ugh, an overflow receptacle pivotally mounted below said coil to catch the overflow therefrom, a trip mechanism including a frame, an arm, pivoted to said frame and connected to said receptacle, a latch carried by said arm, a supporting arm pivoted to said frame and normally engageable by said latch to maintain the latter arm in supporting position, and a valve operating member connected to said valve and having a portion engageable with said supporting arm and released from engagement with said supporting arm-to close said valve by the disengagement of said latch fro-m said supporting arm when said receptacle has moved a predetermined distance about its pivot.

2. In an oil burner, a coil, a supply pipe therefor, a valve in said pipe for controlling the flow of oil to said coil, a trip mechanism suspended from said supply pipe and including a frame, a supporting arm pivoted to said frame, a valve operating member supported by said supporting arm and capable of operating said valve when released from said supporting arm, a second arm also pivoted to'said frame, a latch carried by said second arm and engaging the first-named supporting arm to releasably maintain the same in supporting position, a receptacle for receiving oil from said coil, and a connection between said receptacle will be stopped and any danger of ignition 46 and said second arm for lifting the latter to disengage said latch from said supporting arm when a predetermined quantity of oil has flowed into said receptacle.
